i can play for ireland if my parents are irish?
Yes and if you have claimed dual citizenship as well. Which only requires parents to be Irish or even great grandparents.
So you make the Rules now?
Dual citizenship means you claim both Irish citizenship and British Citizenship which is within the rules is it not?
The rules state "The criteria for a 'Nation' is based on citizenship or birthplace", Dual citizenship is citizenship it does not mean half and half it means both, and it is a legal right, no I do not make the rules as the organiser you have the right to kick me out of the tournament, but I have acted within the rules stated.
